[Closed] So wrong; Pedal with your bars

Wrong on many many levels

now that is a thing..

maybe something to keep the niche whores happy..?

is that how Thomas Voeckler learn't to ride ?

A lot of my power when standing comes from my upper body resisting the pedal strokes so suspect my overall power would be reduced, even though it might give a better uppoer body workout.

Love the white tyres though.

Good, I hate these metal stems you get now, always wanted one made of rubber.

Front wheel drive anyone?

if they (as it appears) are using that movement of the bars to drive the wheels than it would increase efficiency power and speed.

the human powered vehicle folk do this all the time to increase speeds

I'm not too sure that it would increase power or speed, well maybe possibly peak power, but not sustained.
I think that sustained power is ultimately regulated by your aerobic system rather than insufficient muscle recruitment. Using your arms will just mean you get out of breath quicker 🙂

He's crap at wheelies, though.

Mebbe it does, but it still seems wrong to me. I know that using my arms as well as legs will recruit new muscles to drive me forward, but can't help thinking that by losing the ridity of my core/lower back (that my legs brace against) I will be losing more leg power than the arm power I am gaining.

Plus I have heard (somwwhere) that using arms increases heartrate without commensurate gains in output.

We may be back to planes and treadmills teritory here.

Experiment, it's the only way to be sure.

Powertap, turbotrainer, NOW.

However.. when going for it out of the saddle we do pull up on the bars with our arms which has the result of pushing our feet down all the harder on the pedals.. doesn't it..? Thinking about it there must be a fair bit of energy going in to twisting the stem uselessly.

It is actually driving the rear wheels via a series of levers, cables and a chain...

Surely pumping the bars (like a bmx rider) achieves the same without all that extra faff? You unweight and use your whole body for leverage which transfers into the pedals.

Wouldn't want to hit a jump on it!

If you corner leaning, wouldn't it prevent you getting an edge on your tyres too?

What a stupid idea.

probably fine for a road bike but I like the feeling of my bars being connected to the bike whilst riding down a fast technical route and trying to hang onto a bike made of jelly must feel awful....

i suspect this is also the byproduct of legalising canabis 😆

"Exhilarating and fantastic fun" yeah for the first 10 minutes.

We imperiously demand that you do not use the oscillating bar on roads with engine vehicle circulation until you perfectly master the use of it.

Something tells me English may not be their first language

It wouldn't have the same effect though - when pulling on the bars on this thing it actually creates extra forward drive. Its pretty obvious this would give more power than just your legs (whether you're pulling on the static bars or not).

Which is obviously where he got the idea for the stupid bike, without thinking that you don't have to STEER a cross trainer!

I think you can lock it into a horizontal position for when you want to ride something technical.

I've seen a fella with no legs on a recumbnant looking bike where the cranks were the handlebars. Quite a good product i felt and not stupid like that pos.

Those are called handcycles. Seen quite a few in Germany, including one doing an (admittedly small) Alpine pass 🙂

Although the ones I saw were nothing like as awesome as that thing 🙂

yes but you generally have to be an amputee to get one on mobility 😆

I used to sell specialist bicycles to the [i]less able[/i] and hand cycles require massive arm strength, but the sensation of speed is greater as you're sitting an inch off the ground, just don't run over any cats eyes on the road 😯

They're also ideal for those moments when the articulated truck breaks down blocking the road, avoid decapitation by riding right on underneath it...

There’s about 15 minutes of learning to get used to the oscillating bar, and perhaps one hour training to master it.

The system may be forbidden by some governments. Please do check and respect the law of the land.

The wheels, the pedals, and the pedal axle do not turn backwards.

The bar does not do sharp turns when the pedals are not turning. There is some leeway so that there is no problem keeping the equilibrium on a road with no sharp turn, even if the pedals are not turning.

The left pedal is displaced a bit more than one inch on the outside.

This first model is not suited for persons over 85 kilos.

so you can't slow down or back pedal or turn sharply

solution for a non-existent problem

But it gives you one third more power! What's not to like?

i'm gonna play devil's advocate: I like that frame!

hand cycles require massive arm strength

Look at the size of that guy's chest!

Not all hand cycles are like that tho, the ones I've seen pootling about are more like racing wheelchairs than deadly speed machines.

Brilliant...so absolutely no use what so ever. You could only use it in an environment he demonstrated in the video, i.e. wide open spaces with no other people or vehicles, and plenty of room to move about erratically.

'...no problem keeping the equilibrium on a road with no sharp turn...', avoiding people or vehicles would therefore be impossible.

According to the 'tech'...

My system is different from the others in that it makes use of cables and pulleys for transmission, not rod and crank.

The main advantage is that this system has no dead point, and is efficient from top to bottom of the course of the bar.

I was able to conceive this because I have been a sailor…
The base of the rEvolution is the italian high-end FRM bike.
The main change has been bigger chain-rings : 39 and 51 teeth.

It is my feeling that they could be even bigger.

WTF has being a sailor got to do with anything? Does it float?

I like the tag line in the image flamejob posted...

[i]The most powerful bike ever[/i]

I wonder how he qualified that statement...
